Application filed October 1, 1912.- Serial N o. 723,439.

To all whom it may concern Be it Vknown that I, AUGUST l/V. L. HART- BAUER, a citizen of the United States, Aresiding at Chicago, Illinois, have invented a certain new and usefullmprovement in Railway-Car-Deck Ventilators, of which the following is a full', clear, and exact description, such as will enable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanyingv drawings, forming part of this specifi` cation, in which- Figure l is a perspective view of a portion of a railway car deck with my improved ventilator positioned thereon. Fig. 2 is a hori- Zontal section taken approximately on the line 2-2 of Fig. 1. Fig. 3 is a vertical sectiontaken approximately on the line 3-3 of Fig. 1. Fig. 4 is a perspective view of aV portion of a railway car deck, and showing a modified form of the ventilator. Fig. 5 is a vertical section taken approximately on the line 5-#5 of Fig. 4L. Fig. 6 is a horizontal section taken approximately on the line 6-6 of Fig. 5. Fig. 7 is a perspective view of a portion of a railway cardeck, and showing a further modified formV of the ventilator.

This invention, relates toy new and useful improvements in ventilators particularly intended for use on the decks of railway passenger cars, the principal object of my invention being to arrange'on the side of the car deck a simple, inexpensive ventilator having communication with the interior of lthe car, and which ventilator 1s provided with one or more curved or inclined faces against which wind or the air encountered during the movement of the car and its ventilators impinge, and which curved or inv clined faces deflect the wind or air at points near the exit opening of the ventilator, there-l by creating a suction of air from the in` terior of the car through the ventilator.

A further Vobject of my invention is to construct a deck ventilator with the exit opening at the bottom and to provide means on the ventilator adjacent to said exit opening for effectuallyV preventing rain, snow, cinders, dust and like foreign substances from entering the exit opening and passing therethrough tothe interior of the car.

A further object of my invention 1s to provide a deck ventilator through which a suction of air is produced without adjustment of any parts, regardless of the direction in which the car is moving, and fur therto produce a ventilator which Vcan* be cheaply manufactured, and which presents a neat and finished appearance when applied for use.

To the above purposes my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described and claimed.

Referring by Vnumerals to the -accompanying drawings, and particularly to the form of ventilator illustrated in Figs. 1 to 3 inclusive, 1 designates the car deck, 2 the deck posts, 3 an opening between the posts and Llan ordinary form of slotted register located on the interior of the car immediatelv over the opening 3. Applied to the exterior of the deck .immediately over the.

opening is a plate 5, preferably of metal, and formed therein is an opening 6. Fixed 'to this plate at the sides of the opening thereinis a vpair of outyvardlyextending parallel walls 7 the outer ends vof which are bent outwardly away from each other to form a pair of vertically disposed front wallsV 8, which are parallel with the base plate 5. Vertically disposed, longitudinally curved walls 9 extend from pointsnear the ends of the base plate 5 to points onV the walls 7 immediatelyV tothe rear of the front walls 8, .and positioned between the outer ends of these curved walls and theends ,of the frontwal-ls Bare vertically disposed defiecting walls or plates l0, which occupy planes at angles of approximately 45 degrees relative to they planes occupied by the front walls 8 and base plate. These deilecting walls or plates 10 are compara-tively narrow and are arranged so as to deflect the currents of air away from the mouth of the opening 6, thus preventing any tendency of the air after passing over the surfacesV of the curved walls 9 to enter thel mouth vof the opening 6, thereby setting up back drafts to interfere with or, reduce the suction of foul airthrough said open* Fixed in'any suitable manner tothe,

ticular form of ventilator is in service and. the car upon which said ventilator is mountved is in motion the air encountered by the forward one of the curved plates or walls 9 isV deflected outwardlv as shown'by arrows inlF ig. 2, and theL air thus encountered striking against the corresponding angular wall or plate 10 will be deflected outwardly, as shown by arrows immediately in front of and adjacent to the vertically disposed exit opening between the forward ends of the walls 7 rlhis rapid and forceful passage of air across the eXit opening of the ventilator naturally creates a draft or suc` tion of air through the ventilator, and thus air from the interior of the car is drawn through the register el into the opening 3, from whence said air discharges outwardly through the opening between the walls 7.

- It will be noted that the walls or plates which are very narrow are located very close to the mouth of the opening 6, and these plates are arranged so as to direct the air from the curved surfaces of the walls 10 outwardly at an angle relative to the front wall 8 in which the mouth of the opening 6 is formed, and this arrangementV prevents the formation of back drafts through said opening.

By providing the curved plates 9 on both sides of the ventilator the device is adapted to create a suction of air from the interior of the car through the ventilator as the car l is moved in either direction.

lt will be readily understood that when a car equipped with my improved ventilator is at rest or is moving at a very slow speed, wind which may be blowing in a direction lengthwise of the car will Vimpinge against either one of the curved plates 9, thereby creating suction through the ventilator to draw air from the interior of the car. The draft of air from the interior of the car can be readily regulated by a proper manipulation of the register et.

In the modified construction illustrated in Figs. -l to 6 inclusive the main body of the ventilator comprises a box-like structure 13 provided with an extension 14 which communicates with the Vinterior of the car, and in this form of device the exit opening is located at the bottom of the structure 13. Extending downwardly and outwardly from the top of the structure 13 at both ends and at the outer side are inclined plates 15, and positioned between the lower ends of these plates and the corresponding lower ends of the end and outside walls of the structure 13 are curved plates 16. Extending outwardly and downwardly from the lower ends of these curved plates 16 are comparatively narrow deiiector plates 17 which are arranged at angles of approximately 45 degrees relative to a vertical plane. In this form of device a screen of section of wire netting 18 4is located in the exit opening at the lower end of the structure 13, and if desired a series of inclined delector plates 18?L may be arranged beneath this screen, thereby preventing rain, snow, cinders and the like from entering the ventilator. rlhe action and operation of this form of ventilator is identically the same as the action and operation of the form of ventilator previously described, and in addition this second form of ventilator has the advantage of producing a suction of air from the interior of the car while said car is standing still, and wind from any one of three directions impinges against the in- -clined plates 16.

In the modified construction of the ventilator seen in Fig. 7 the main body of the ventilator is surrounded by a semi-circular shell 19 having an inwardly Y and downwardly curved face 20 from the lower edge of which projects outwardly and downwardly an inclined deflecting member 21. 1n this form of device air or wind striking against the curved surface 20 is deiiected downwardly, thence outwardly by the deflccting flange or member 21, thereby setting up a suction of air through the ventilator.

A ventilator of my improved construction is very compact, presents a. neat and finished appearance when applied for use, can be manufactured at comparatively little cost, and in service is very effective in drawing air from the interior of the car to which it is attached.

1t will be readily understood that minor changes in the size, form and construction of the various parts of my improved ventilator can be made and substitutedfor those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims. y f
